How to Split and strip into multiple variables?

Question

How to Split and strip X string values into separate variables?

X has string value of

itemA=myvalue&itemB=anothervalue&itemC=andanother

I have 3 strings (var1,var2,var3) to hold the values of the stripped values.

Find in string X "itemA=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var1)

Find in string X "itemB=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var2)

Find in string X "itemB=" copy everything after "=" character until "&" character OR if no "&" character is found copy until end of string (store this value into var3)

Answer 1

string X =  "itemA=myvalue&itemB=anothervalue&itemC=andanother";
string[] variables = X.Split('&');
 foreach (var variable in variables)
 {
    string key = variable.Split('=')[0]; //Ex. itemA
    string value = variable.Split('=')[1]; //Ex.myvalue
    //do whatever you want with the value 
}

Answer 2

Using System.Web.HttpUtility. You can use this even in a non Web application, if a reference to System.Web is not a problem.

var values = HttpUtility.ParseQueryString(
    "itemA=myvalue&itemB=anothervalue&itemC=andanother");

Console.WriteLine(values["itemA"]);
Console.WriteLine(values["itemB"]);

You can list all the keys:

foreach (var key in values.AllKeys)
{
    Console.WriteLine(key);
}

Answer 3

If its asp.net application, you can use QueryString.

string value1 = Request.QueryString["itemA"];
string value2 = Request.QueryString["itemB"];
string value3 = Request.QueryString["itemC"];

Answer 4

string[] pairs = mystring.Split( '&' );
var1 = pairs[0].Split( '=' )[1];
var2 = pairs[1].Split( '=' )[1];
var3 = pairs[1].Split( '=' )[1];
